\nThe statement that is NOT true regarding infrared radiation is that it is a longitudinal wave. Infrared radiation is a part of the electromagnetic spectrum. All electromagnetic waves, including visible light, radio waves, UV rays, X-rays, gamma rays, and infrared radiation, are transverse waves. In transverse waves, the oscillations (of electric and magnetic fields) are perpendicular to the direction of wave propagation. Longitudinal waves, such as sound waves in air, involve oscillations parallel to the direction of propagation.

\nInfrared radiation is electromagnetic in nature, meaning it consists of oscillating electric and magnetic fields and travels at the speed of light in vacuum. Its wavelength range is typically longer than that of visible light (from about 700 nanometers to 1 millimeter). Like all electromagnetic waves, it can travel through vacuum. Infrared radiation is commonly associated with heat transfer (thermal radiation).
